Oakland police identified the remains as those of 50-year-old Sandra Coke of Oakland on Tuesday.

A Northern California judge has revoked the parole of a registered sex offender considered a person of interest in the death of federal investigator Sandra Coke.

Randy Alana appeared in an Alameda County courtroom Friday to face allegations that he'd violated his parole by contacting Coke, failing to charge his GPS monitor, resisting arrest and absconding from parole.

Alana was arrested on Aug. 6 for violating his parole, two days after Coke was reported missing after leaving her Oakland home.

Police say Coke was last seen with Alana, whom she briefly dated about 20 years ago.

Coke's body was found Aug. 9 in Vacaville.

Alameda County prosecutor Paul Hora says Oakland Police are still investigating Coke's death and Alana has not been charged.
